基于深度协作神经网络的电影推荐

Integrating User and Item Reviews in Deep Cooperative Neural Networks for Movie Recommendation

University of Patras(帕特雷大学)

Aristeidis Karras, Christos Karras

摘要:

用户评价包括在线平台上的大量信息。这种信息源被大多数现有的推荐系统所忽视,尽管它有可能缓解稀疏性问题并提高建议的质量。这项工作提出了一个深度模型,用于从评论文本中同时学习项目属性和用户行为。深度合作神经网络(DeepCoNN)是由两个并行的神经网络在其最后一层连接而成的建议模型。其中一个网络专注于从用户提交的评论中学习用户行为,而另一个网络则从用户评论中学习物品属性。在顶部,添加了一个共享层来连接这两个网络。与因子分解机器方法类似,共享层允许为人和事物获取的潜在因子彼此交互。根据实验结果,在许多数据集上,DeepCoNN超过了所有基线推荐系统。

英文摘要:

User evaluations include a significant quantity of information across online platforms. This information source has been neglected by the majority of existing recommendation systems, despite its potential to ease the sparsity issue and enhance the quality of suggestions. This work presents a deep model for concurrently learning item attributes and user behaviour from review text. Deep Cooperative Neural Network (DeepCoNN) is the suggested model consisting of two parallel neural networks connected in their final layers. One of the networks focuses on learning user behaviour from reviews submitted by the user, while the other network learns item attributes from user reviews. On top, a shared layer is added to connect these two networks. Similar to factorization machine approaches, the shared layer allows latent factors acquired for people and things to interact with each other. On a number of datasets, DeepCoNN surpasses all baseline recommendation systems, according to experimental findings.
